This is not really the place for this question as the people here are mostly users, not Adobe employees (though they are here). This forum is to answer technical and production questions.
However just google search "adobe cc cancellation policy" and you should find what you need.
You'll need to check your Adobe cancellation policy, in your country, but I would think that - assuming you are on month-to-month subscription - if you cancel you probably won't get a refund for the month you have started once you pass 14 days.
At least that appears to be the case for my country.
You should be able to reactivate your subscription later if you want using the same account. But as I said you'll need to check with Adobe. This will probably require a phone call.
